{Warning
Inappropriate installation or
removal of audio, radio or other
electrical equipment can
adversely affect other electrical
equipment and cause a
breakdown or fire. Be sure to
have electrical equipment
installed or removed by your
dealer. You and others could be
seriously injured.
Do not install any unauthorized
radio set, or any radio set or
antenna that does not comply with
relevant standards. Noise from the
radio set could cause
electromagnetic interference with
the vehicle's electronic equipment and other systems, resulting in a
vehicle breakdown or in a
malfunction of electronic equipment.
Consult your dealer if you wish to
install radio equipment.
Power Take-Off (PTO)
If equipped, the PTO is a device
that is used to provide engine power
to special equipment directly from
the engine or through the
transmission. For details about the
PTO operation, refer to the separate
instruction manual provided by its
maker.
If the optional PTO function is used
for long periods of time, make sure
to regularly check the diesel
particulate filter (DPF) indicator.
Automatic DPF regeneration will not
take place while the PTO function is
active.

Underbody Maintenance
Corrosive materials used for ice and
snow removal, and dust control can
collect on the underbody. If these
materials are not removed,
accelerated corrosion (rust) can
occur on underbody parts such as
fuel lines, frames, floor pan and
exhaust system even though they
have been provided with corrosion
protection.
At least every spring, flush these
materials from the underbody with
plain water. Take care to clean well
any areas where mud and other
debris can collect. Sediment packed
in closed areas of the frame should
be loosened before being flushed.
If desired, your authorized dealer
can do this for you.
Interior Care
General
Remove dust and dirt from the
interior of the cab using an
automotive cleaner or vacuumcleaner, and gently wipe surfaces
clean using a cloth wet with warm or
cold water.
{Warning
Water should never be sprayed
directly into the interior of the cab
when cleaning. Failure to observe
this precaution can lead to vehicle
malfunction and possibly to fire if
water should enter the audio
system or other electrical
components located underneath
the floor carpet.
Petroleum ether, gasoline and
other organic solvents should not
be used to clean safety belts. In
addition, safety belt webbing
should be neither bleached nor
redyed. Failure to observe these
precautions can lead to the
performance or strength of the
safety belts being impaired. In the
case of a collision, therefore, the
safety belts could be insufficiently
effective, and serious
(Continued)
Warning (Continued)
life-threatening injuries could
result. When cleaning, use warm
water in which a small amount of
neutral detergent has been
dissolved to gently wipe the
safety belts.
Follow the manufacturer's advice
whenever cleaning agents or
other chemicals are used, inside
or outside the vehicle. Some
cleaners may be poisonous or
flammable, and improper use may
cause personal injury or damage.
When cleaning the inside or
outside of the vehicle, do not use
volatile cleaning solvents, such as
acetone, lacquer thinners, enamel
reducers, nail polish removers; or
such cleaning materials as
laundry soaps, bleaches or
reducing agents, except as noted
in the following fabric cleaning
advice on stain removal. Never(Continued)

314 Vehicle Care
Warning (Continued)
use carbon tetrachloride,
gasoline, benzene or naphtha for
any cleaning purpose.
Open all vehicle doors for
ventilation when ANY cleaning
agents or other chemicals are
used in the interior. Overexposure
to some vapors may result in a
health problem that is more likely
to occur in small, unventilated
spaces.
You and others could be seriously
injured.
The interior of the vehicle must
never be cleaned using acidic or
alkaline solvents, or petroleum
ether, gasoline, and other organic
solvents. Failure to observe this
precaution can result in
discoloration and staining. It should
be noted that certain types of
cleaning products contain these
compounds. Be sure to read
cleaning product labels carefully. Air fresheners (liquid, solid, gel,
or plate types) must not come into
direct contact with, or spill onto,
interior components such as the air
conditioning or audio system.
Compounds contained in these
products can cause discoloration,
staining, or peeling of paint.
Glass cleaners that contain these
compounds must not be used to
clean the inside of the windshield or
window glass. To clean the glass,
wipe it using a cloth wet with warm
or cold water.
To avoid possible permanent
discoloration of light colored seats,
Do not let materials with non-fast
colors come into contact with seat
trim materials until these materials
are totally dry. This includes certain
types of casual clothing, such as
colored denims, corduroys, leathers,
and suedes, as well as decorative
paper.
With the use of modern trim
materials, it is very important that
you use proper cleaning techniques
and cleaners. Failing to do this on
the first cleaning may result in waterspots, spot rings, or setting of stains
or soilage
—all of which are more
difficult to remove in a second
cleaning.
Dust and loose dirt that collect on
interior fabric should be removed
often with a vacuum cleaner or soft
bristle brush. Wipe vinyl or leather
trim regularly with a clean, damp
cloth. Normal trim soils, spots,
or stains can be cleaned with these
cleaners.
Remember these basic steps before
cleaning:
. Remove stains as quickly as
possible before they set.
. Use a clean cloth or sponge,
and change to a clean area
often. A soft brush maybe used
if stains persist.
. Use solvent-type cleaners only
in a well ventilated area: also, do
not saturate the stained area.
. If a ring forms after spot
cleaning, clean the entire area
immediately.
